There are at least two couples that stayed married on The Bachelor! And they switched it up for a week, as Molly Mesnick (née Malaney, season 13) went to Dallas to play wife-for-a-week to Sean Lowe (season 17) while Catherine Lowe (née Giudici, season 17) temporarily shacks up with Jason Mesnick (season 13). Hijinks naturally ensued, and in the end, they lived happily ever after. After they each got back with their regular husband/wife and back to their own house.
